Title5E40.60 - Elementary Storage Cell with Bell
Objective

Demonstrate a simple lead-acid battery that can be charged and then used to power a bell.​

StatusAvailable
Assembly Instructions

Overview
Charging is a process whereby lead sulfate forms on the plates, and during charge is converted to lead dioxide (positive plate) and pure lead (negative plate).This process eventually results in a Fractal surface, with far greater surface area being exposed.This increases the current the cell can deliver.
Instructions
The two lead plates, immersed in a 30% solution of sulfuric acid, are connected to the middle terminals of the double-pole-double-throw switch. Two of the other terminals should be connected to the dry cell for charging the storage cell. To initially start the battery use 12 VDC then switch to the 6-V dry cell. The other two terminals are connected to the bell. After the lead cell has been charged by the dry cells for a few seconds, the switch is thrown over to connect the storage battery to the bell.
